PACK OF RING SPRINGS WITH DAMPER Russian patent published in 2017 - IPC F16F3/10 F16F1/32 

FIELD: machine engineering.

SUBSTANCE: pack of ring springs consists of a set including two pairs of oppositely located and interconnected large bases of circular elastic conical discs. Inner toroidal surface is formed in the joint of each pair. Outer toroidal surface is formed in the joint of the set of these pairs at smaller base. Each of the disks has a side conical surface with spherical segments located at the larger and smaller bases of the truncated cone. The spherical segments are directed in opposite directions from the generatrix of the conical surface. The pack of ring springs is located in cylindrical housing with groove whose lower part is rigidly connected with base. Base has centering cylindrical collar made of sintered friction material based on copper into which smaller base of one of pairs of disks is inserted. Each disk has three radial slots terminating in hole. The lid with centering cylindrical collar is installed movably with the clearance in top part of the casing. A lubricant, for example grease, is introduced into the cavity between the cover and the adjacent disk. The cavity between the base and the adjacent disc is filled with polyurethane. Cavities formed between the pairs of discs are filled with crumb of vibro-damping material.

EFFECT: increased efficiency of vibration isolation in resonance mode.
